Types of Protozoa
Amoebozoa is a major taxonomic group containing about 2,400 described species of amoeboid protists, often possessing blunt, fingerlike, lobose pseudopods and tubular mitochondrial cristae. In most classification schemes, Amoebozoa is ranked as a phylum within either the kingdom Protista or the kingdom Protozoa.
Some protozoa have two-phase life cycles, alternating between proliferative stages (e.g., trophozoites) and dormant cysts. As cysts, protozoa can survive harsh conditions, such as exposure to extreme temperatures or harmful chemicals, or long periods without access to nutrients, water, or oxygen for periods of time.
Protozoa are microscopic, one-celled organisms that can be free-living or parasitic in nature. They are able to multiply in humans, which contributes to their survival and also permits serious infections to develop from just a single organism.

Sarcodina /Sar·co·di·na/ (-di´nah) a subphylum of protozoa consisting of organisms that alter their body shape and that move about and acquire food either by means of pseudopodia or by protoplasmic flow without producing discrete pseudopodia.
Phylum Sarcomastigophora includes both free-living and parasite protozoans. The cell size is usually between 10 and 30 micrometers. Like other The cell size is usually between 10 and 30 micrometers.
Tritrichomonas foetus is a microscopic single-celled flagellated protozoan parasite that has traditionally been identified as a cause of reproductive disease in cattle (infertility, abortion and endometritis).
